Definitions

  • the present invention relates to a system, called a pantograph, for supplying electric current to an electric traction train from overhead conductors or catenary wires.
  • the invention relates to systems making it possible to improve the electrical contact between the upper element of the pantograph, called a bow, and the catenary wire.
  • a device of the so-called air cushion type comprising a pneumatic member constituted by two parallel flanges connected at their periphery by an element in the form of an elastic bellows, the first flange being integral with the structure of the driving car and the second flange which can undergo a displacement of limited magnitude.
  • the bellows When the bellows is inflated with a gas, such as compressed air under a determined pressure, the folds of the bellows are expanded, which causes a displacement of the movable flange. This movement is made to correspond to a movement of rotation of the axis of a lower arm of the pantograph, this movement of rotation allowing to exert a certain pressure of the bow against the catenary.
  • a gas such as compressed air
  • the locomotive running on the track the above device plays, to a certain extent, the role of a return spring of particular characteristics.
  • the movable flange To ensure an approximately horizontal movement of the movable flange, it is generally made integral with the end of a substantially vertical rod fixed at its lower end, in an articulated manner, to the structure of the motor car.
  • the above rod is relatively long and capable of substantially horizontal movement at its upper end, which allows it to serve as a guide for the movable flange, during the movement of the latter of limited amplitude. It is necessary to use a rod long enough so that the displacement of the flange is comparable to a straight line.
  • the device of the above air cushion type, and more particularly its guidance system has various drawbacks: - the guidance system is relatively complex and heavy, which increases the inertia of the assembly and affects the performance of the pantograph, insofar as an increase in inertia leads to an increase in the response time of the assembly as a whole disturbance system, - the length of the rod, imposed by the need to have at its end a displacement comparable to a straight line, makes the guide system bulky, - The guidance system does not prevent a certain buckling of the bellows from occurring, which can introduce a difference in the movement of the flange when the device returns to an equilibrium position from which it has been momentarily moved away and consequently a gap unjustified in the pressure of application of the bow, - the guidance system is exposed to dust, aggressive agents, atmospheric precipitation, and requires relatively frequent monitoring and maintenance operations.
  • the object of the present invention is to propose a new device for a pantograph which makes it possible to greatly reduce the above drawbacks.
  • the subject of the present invention is a pantograph for an electric traction locomotive comprising a bow making electrical contact with a catenary wire and an elastic device of the air cushion type for pressing the bow against the catenary wire by means of a torque exerted on an axis of a lower arm of the pantograph, characterized in that said elastic device comprises: - a first flange secured to the structure of the locomotive, - located opposite the first flange and connected to the latter by means of a wall constituted by an elastic material, a second flange movable relative to the first flange, the two flanges forming with said elastic wall a sealed enclosure containing a gas, and in particular air, under a pressure which may be different from atmospheric pressure, - disposed inside the sealed enclosure, a means for guiding the second flange constituted by an elongated member, the two ends of which are connected in an articulated manner each to a flange, this means allowing said second flange to move in a movement substantially translational with
  • the invention relates to the combination of a device according to the first aspect of the invention and of means making it possible to vary the pressure of compressed air in said sealed enclosure in order to apply the bow on the catenary wire with a determined pressure, and said determined pressure which can itself be programmed as a function of parameters linked to the environment of the pantograph: vertical distance from the catenary wire to the track, speed of the locomotive, etc.
  • the device described above could be advantageously associated with a sensor-based system such as that described in French patent application n ° 89 05653 of April 28, 1989, this system comprising in particular force sensors placed in close proximity to the friction strips by which the bow leans against the catenary wire and the data from the sensors is transmitted by a bundle of optical fibers to an electronic control unit actuating a pneumatic solenoid valve.
  • a sensor-based system such as that described in French patent application n ° 89 05653 of April 28, 1989, this system comprising in particular force sensors placed in close proximity to the friction strips by which the bow leans against the catenary wire and the data from the sensors is transmitted by a bundle of optical fibers to an electronic control unit actuating a pneumatic solenoid valve.
  • FIG. 1 shows a pantograph 1 comprising a basic structure 2 allowing it to be mounted on the roof of a locomotive, or more generally of a railway train, not shown.
  • the structure 2 is provided with mounting flanges 3.
  • an pneumatic actuator cushion 4 acting on an axis 7 of a lower arm 8 of the tubular structure, of the pantograph.
  • the lower arm 8 is connected to an upper arm 11, also tubular, by a main articulation 12.
  • the pantograph 1 further comprises parallelogram bars, lower and upper, respectively 13 and 14.
  • the arm 11 carries, at its upper end, a bow 16 ensuring contact with a non-catenary wire represented.
  • the bow 16 comprises an armature 17 provided with two friction bands 18.
  • the pneumatic actuator cushion 4 is shown in more detail in FIGS. 2 and 3. It comprises a first flange 21 and a second flange 22 of substantially circular shape, connected by means of a rubber bellows 23.
  • the bellows 23 has a conformation generally substantially cylindrical such that the two flanges are substantially coaxial.
  • the flange 21 is secured to the roof of the locomotive by successively an element 24 of the structure 2, secured by means of bolts 26, then the flange 3 and an insulator 27.
  • the flanges 21, 22 define with the bellows 23 a sealed enclosure 28, which communicates with a pneumatic supply, not shown, by means of an opening 29 made in the first flange 21.
  • Each flange 21, 22, carries, inside the enclosure 28, a tab 30, 31, the two tabs being arranged in the same plane perpendicular to the two flanges and substantially median with respect to each of them, on either side of the axis at the same distance from it.
  • the legs 30, 31 intended to fix a link 32 which can pivot about axes 33, are arranged so as to be symmetrical with respect to an axis substantially perpendicular to said median plane and meeting the link (32) substantially in the middle of its elongated part .
  • an actuator member comprising two arms 34 arranged symmetrically with respect to a vertical axial plane of said flange and connected by a substantially horizontal spacer 36.
  • the spacer 36 To the spacer 36 are fixed the two ends 37 of two wire slings d steel 38 passing along two cams 39 integral with the axis 7 of the lower arm 8 of the pantograph.
  • the slings 38 being themselves integral in rotation with the axis 17, the translational movement of the spacer 36 is transformed into a rotational movement of the axis 7 of corresponding amplitude.
  • FIG. 2 there is shown in dashed position 22a occupied by the flange 22 when the internal pressure of the sealed envelope 28 has been increased to a certain value.
  • the position 22a corresponds to the position 30a of the tab 30, the position 32a of the link 32, the position 38a of the sling 38, the position 39a of the cam 39, and finally the position 8a of the lower arm 8 of the pantograph.
  • the guidance system according to the invention has many advantages, in particular the following:
  • the rod 32 works practically only in tension and compression, that is to say under very favorable conditions for a metal part. This constitutes an important advantage, in particular from the point of view of longevity, compared with the guiding devices used previously, such as the device with external rod previously described.
  • the guide member located inside the airtight enclosure 28 of the air cushion, is protected against any action by the environment (dust, precipitation, aggressive agents). This allows a substantially constant coefficient of friction to be maintained for moving parts.
  • the guidance system according to the invention does not affect the overall height of the actuator system, since it is entirely inside the sealed enclosure, and this constitutes a very favorable characteristic for a device fixed on a medium moving at high speed.
  • the guidance system also does not affect the overall length of the actuator system, since it is possible to accommodate it in the space remaining free in the sealed enclosure when the latter is in the contracted position (air pressure minimal).
  • the link 32 is substantially parallel to the two flanges 21, 22 for an average operating position corresponding to the average operating position of the pantograph.
  • the link 32 in its movement, can take different positions between two extreme positions, inclined with respect to a median plane parallel to the two flanges and substantially symmetrical with respect to this plane.
  • This arrangement facilitates obtaining a translation of the second flange 22 in which the latter remains substantially coaxial with the first flange 21.
  • the precision of such a device does not depend practically no greater or lesser distance between the two flanges.
  • the device according to the invention has the advantage of greater simplicity and greater lightness, that is to say of a lower inertia.
